In the last few weeks. I dropped a glass roasting dish on my bad leg and had blood pissing out of my foot and realized how little people know about first aid when they were more interested in cleaning up the mess than stopping the blood flow.
Tonight I cooked roast chicken with harissa, garlic and oregano with roast potatoes, sweet potato, pumpkin, and carrot (I like cooking) when a mate choked on a piece of chicken. All the first aid and first responder courses paid off when I managed to stop him choking, when he spat out a 3 inch piece of chicken from his throat.
No panicking, no not knowing what to do, just got in there and responded with instinct. Do a First Aid Course.
